    im trying to hook the power steering pump back up in my 93.

    im looking for a diagram on where the 2 lines off the pump go to.

    the car doesn't have a cooler, will a pump failure be unavoidable without it?

    Do not attempt to do this job without good jackstands.

    The return hoses are all low pressure and are most commonly secured to the pump and associated plumbing with worm gear hose clamps. After a while they will frequently soften up at the end where they are clamped, and should be replaced. The auto parts store will sell you hose by the foot and it takes about 3 feet or less, depending if you have the fluid cooler in the low pressure side of the line.

    Each hose uses an O ring on each end to seal them. The hoses will swivel when they are installed and tightened into place. That is why there are O rings on the fittings. The O ring is the part that actually makes the pressure seal. If you slide the nut all the way back as far as it will go, you will see the O ring and the groove cut into the center section of the fitting.

    Sometimes you will get some white Teflon rings with the pump or rack. The rings go on the threaded part of the fitting to reduce or prevent small leaks. They are not meant to seal the pressure part of the line or substitute for the rubber O ring. Heat the white Teflon seals in hot water and they will be easier to install. You can install the fittings without them and not have any leaks if the O rings seal good.

    You may find it is easier to drop the rack down to get to the hose fittings. The flex coupling for the steering shaft needs to be disconnected before you can get the rack out. You should disassemble the coupling by undoing the 2 bolts that hold it together.

    Remove the two bolts that bolt the rack assembly to the frame and then pull the rack down. Get a catch pan to dump the fluid in when you disconnect the hydraulic lines. I replaced the rack mount bushings with some Energy Suspension urethane ones. When you re-install the rack assembly, put the rear bushings in the rack assembly and lift it into place. Then install the front bushings & washers and tighten down the nuts. Doing it this way makes room for the hydraulic lines without having them bind against the frame.

    Time to do the job:
    It takes 20 minutes to get the car up on jackstands.
    It takes 20 minutes to disconnect the steering joint (rag joint). WD40 is your friend, so squirt the 2 rag joint coupler bolts with plenty of it. Do not attempt to disconnect the rag joint from the rack by removing the clamp joint bolt. It is hard to get apart and hard to align and put back together.

    It takes 10 minutes to remove the two mount bolts that secure the steering rack to the k member.

    It takes 10 minutes to remove the front rubber bushings and washers from the rack to K member mount so that you can slide the rack forward and then down.
    You do not need to disconnect the rack from the tie rod ends, or remove the tie rod ends from the steering knuckles.

    It takes 5 minutes per hydraulic line to disconnect them from the rack. Get a catch pan to dump the fluid in when you disconnect the hydraulic lines.

    Total disassembly time roughly 1 1/2 hour, allowing time for some of the bolts to be rusty or hard to turn...

    Figure a little more to reinstall and you have 2 3/4 to 3 hours total time. It you have an impact wrench, subtract 20-30 minutes from the total time

    I told you they only go in 1 spot. I doubt like i said the cooler makes a dam unless your going to be constantly turning the wheel. Like i said thats why you dont get under drive pullies for power steering cause it dont rob power unless you turn the wheel.Still got the looped hose off the 93? peace
